DAVID C. BAUGHMAN, OF ALBION, INDIANA.

SELF-EXT INGUISHING LAMP.

SPECIFICATION forming part of Letters Patent No. 249,874, dated November22, 1881.

Application filed September 13, 1881. (Model.)

To all whom it may concern:

BeitknownthatI, DAVID C. BAUGHMAN, of Albion,in the county ofNoble, andin the State of Indiana,haveinvented certain new and useful Improvementsin Self-Extinguishing Lamps; and I do hereby declare that the followingis a full, clear, and exactdescription thereof, reference being had tothe accompanying drawin gs, and to the letters of reference markedthereon, making a part of this specification.

This invention relates to certain improvements in that class of self orautomatically extinguishing lamps in which the flame is extinguished atan appointed time by suitable mechanism operated by means of a float inthe oil-reservoir, which falls as the oil or burning fluid is consumedand throws or permits the extinguisher to fall over the wick.

The object of the present invention is to simplify the construction ofsuch extinguishers, to dispense with the use of springs, and pro vide amore efficient and reliable device for the purpose than heretofore.These objects I attain by the apparatus and devices illustrated in theaccompanyingdrawings, in which Figure 1 represents a side elevation ofmy improved lamp with a portion of the wall of the reservoir or fountbroken away, showing the float therein. Fig. 2 represents a top view ofthe burner and extinguishing devices, and Fig. 3 represents a detachedview of one of the extinguishingshields. Fig. 4 represents a detachedview ofthe burner, showingthe extinguishing-wings fully separated, inwhich such wings are represented as curved, being a modification of myinvention; and Fig. 5 indicates a vertical sectional view taken on theline m w of Fig. 1.

The letter A indicates the body or reservoir of the lamp, which may beof the ordinary or any approved construction.

B indicates the burner, which is provided with the usual wick-tube, (J.

The letter D indicates the cone or deflector, which is seated on theburner-cap in such position as to fall properly over the wick of thelamp, as usual.

The letters E E indicate two wings or shields,

' which are located one at each side of the wicktube, and which aresecured to the rods F F,

journaled in suitable bearings in the burner.

The said rods at one sideproject beyond their bearings and are bent atright angles, as shown in Fig. 4 of the drawings. The rod F from itshorizontal bend is bent vertically downward, as indicated by the letterGr, Fig. 3, the vertical portion being provided with a series ofgraduations, H, for the purpose hereinafter described.

The letter I indicates a float located in the reservoir of the lamp andattached to a rod,I, extending through a packed opening, K, at the topof the lamp. The said rod is beveled atits upper end, and is adapted tobear against the vertical portion of the rod F, so as to separate theshields and hold them away from the wick-tube while the lamp is burning.The bent arm of the rod F lies in conjunction with the horizontalportion of the rod F, so that the two shields will be operatedsimultaneously.

The letter H indicates a lateral lug on the end of the rod I, whichprevents therod from dropping through the opening K when the floatfalls.

The letter M indicates a stop secured to the top of the lamp, which isadapted to engage the wick-raising shaft and arrest the burner at theproper point, when screwed home, to bring the rods F and I in properconjunction.

The float is oblong in shape, and is located in a chamber formed by asuitable partition in the lamp, which prevents said float from turning,thus holdingtherod I in properposition.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In combination with the burner and wicktube of a lamp, the wings orshields secured to the pivoted rods having their ends bent, asdescribed, one of said rods beingprovided with a vertical graduatedextension and the float and its stem, the latter being adapted, whenelevated, to engage the graduated portion of the rod operating theshields, substantially as and for the purposes specified.

In testimony that'I claim the foregoing I have hereunto set my hand this5th day of September, 1881.

D. O. BAUGHMAN.
